Critical Care Nursing Practice Questions

Correct Answer: A

Rationale: Rationale: Accurately identifying patients is a National Patient Safety Goal to prevent errors in patient care. Proper patient identification ensures correct treatments and medications are given, reducing harm. Restraint elimination, medication reconciliation, and infection reduction are important goals but not specific National Patient Safety Goals. Accurate patient identification directly addresses patient safety concerns.

Correct Answer: A

Rationale: The correct answer is A because it aligns with the ethical principle of patient autonomy, which emphasizes the patient's right to make decisions about their own care. Withholding or withdrawing life-sustaining treatments, including nutrition, antibiotics, and blood products, respects the patient's autonomy. This choice also reflects the principle of beneficence, as it aims to prevent unnecessary suffering and respects the patient's wishes. Option B is incorrect because it focuses on pain and anxiety management rather than the broader ethical considerations of withholding life-sustaining treatments. Option C is incorrect because withdrawing life-sustaining treatments while a patient is receiving paralytic agents can pose additional risks and complications, potentially conflicting with the principles of nonmaleficence and beneficence. Option D is incorrect because the primary goal of withdrawing or withholding treatments is not to hasten death but to respect the patient's autonomy and quality of life. This choice does not align with the ethical principles of patient-centered care.

Correct Answer: C

Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries. A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism. B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism. D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.

Correct Answer: A

Rationale: The correct answer is A: Clinical practice guidelines. Clinical practice guidelines are evidence-based recommendations that assist nurses in providing appropriate care based on research. They outline best practices for specific patient populations or conditions, helping nurses make informed decisions. Summary: - B: Computerized physician order entry: While it may improve accuracy and efficiency, it does not specifically ensure care based on research. - C: Consulting with advanced practice nurses: While collaboration is valuable, it does not guarantee care based on research. - D: Implementing Joint Commission National Patient Safety Goals: Important for patient safety, but not directly related to ensuring care based on research.

Correct Answer: C

Rationale: The correct answer is C: A woman who originally escorted the patient in. This choice is correct because she is most likely the person responsible for the patient's care and thus likely has legal authority to make medical decisions on behalf of the patient. The other choices are incorrect because simply being recognized as the patient's brother (A), being a teenage boy who approaches the nurse (B), or being a woman whom the others look at and call over (D) does not necessarily indicate that they have the legal authority to make medical decisions for the unconscious patient.
